q690d proportion

Our steels have been widely applied to many industries and fields, such as the construction industry, shipbuilding industry, pressure vessels and boilers, oil and gas, bridge construction, offshore platforms, stamping cold forming,etc.

Experimental study on fatigue performance of high strength ...

The code values were relatively conservative, and the fatigue life of Q690D base material was clearly underestimated. (2) With respect to Q690D butt weld specimens, the AISC360 and EC3 curves generally overlapped, and the fatigue limit was about 90 MPa. The 95% survival probability curve was above the code curves, but the slope was smaller.[PDF]
